Buying Guide

Key considerations when selecting a propane-capable generator include power needs, fuel flexibility, and safety features. Start by estimating the running watts required to support essential circuits, then select a model with headroom to handle startup surges. Fuel availability and storage considerations influence whether tri-fuel or dual-fuel designs best fit your location and usage patterns. Look for automatic CO detection and shutoff features to reduce environmental risk, especially in enclosed spaces. Transfer-switch compatibility is important for whole-home backup, ensuring consistent power to critical loads. Noise level, portability (wheel kits, handles), and run-time at typical loads also affect daily usability. Finally, prioritize models with durable construction, robust engines, and reputable warranties to maximize long-term reliability.
